Answer:
x= 19
Step-by-step explanation:
Is given that the <u>triangles are congruent</u> so the corresponding sides are congruent as well.
Also congruent sides are equal in measure so we use the given picture to write the equality.
2x -1 = 37, add 1 to both sides
2x = 38 , divide both sides by 2
x = 19

Answer:
81/42
Step-by-step explanation:
8 1/10 ÷ 4 1/5
81/10 ÷ 21/5
81/10 * 5/21
(81*5)/(10*21)
405/210
81/42
Change that into a mathematical inequality and you get
n>_ -1.5
n is greater than or equal to -1.5
Hope this helps :)
